Cylindrical Lenses of various specifications and different radii can be produced by He Rui optics, using different glass materials (Schott, Ohara, CDGM, fused silica,MgF2, CaF2,ZnSe,ZNS, etc.).
For example: plano-convex cylindrical Lenses, plano-concave cylindrical lenses, double-convex cylindrical lenses, double-concave cylindrical lenses, crescent cylindrical lenses.
We can also produce special cylindrical mirrors, such as achromatic cylindrical lenses, parabolic mirrors, cylindrical ellipsoidal lenses and double-curvature cylindrical lenses, such as aspheric cylindrical lenses and glued cylindrical lensess. In addition, we can even produce cylindrical Lenses with complex shapes, such as fan-shaped cylindrical lensess, off-axis cylindrical lenses, and angular cylindrical s. According to customer requirements, it can be customized to include special glass materials such as ultraviolet and infrared quartz, as well as crystal materials like calcium fluoride.
